The nurse is reviewing her hospitalized client's medications and sees that he is on both a cephalosporin and an aminoglycoside. The nurse knows that this combination of antibiotics increases the client's risk for:
Seizures.
nephrotoxicity.
hearing loss.
Hepatotoxicity.
The Correct Answer is B
A. Seizures: Some antibiotics, especially cephalosporins, can lower the seizure threshold, increasing the risk of seizures, especially in individuals prone to seizures or those with a history of epilepsy.
B. Nephrotoxicity: Both cephalosporins and aminoglycosides have the potential to harm the kidneys. When used together, their nephrotoxic effects can be additive, increasing the risk of kidney problems in patients.
C. Hearing Loss: Aminoglycosides, a class of antibiotics that includes drugs like gentamicin, are well-known for their potential to cause hearing loss, especially when used in high doses or for prolonged periods. This effect is due to their toxic impact on the hair cells in the inner ear.
D. Hepatotoxicity: Hepatotoxicity refers to liver damage caused by medications. Some antibiotics, including certain cephalosporins, can have hepatotoxic effects, potentially harming the liver. Monitoring liver function is important when these drugs are used.

Correct Answer is B
Explanation
A. Antibiotics are prescribed according to culture and sensitivity reports:
When antibiotics are prescribed based on specific tests like cultures and sensitivity reports, it ensures that the right antibiotic is chosen for the specific bacteria causing the infection. This practice helps in targeting the infection more effectively, reducing the risk of antibiotic resistance.
B. Patients stop taking an antibiotic after they feel better:
This scenario is problematic. When patients start feeling better, they might assume the infection is completely gone and stop taking antibiotics before the prescribed course is finished. This premature discontinuation can leave some bacteria alive, which may develop resistance to the antibiotic used. This practice is a significant contributor to antibiotic resistance.
C. Antibiotics are taken with ascorbic acid (vitamin C):
Ascorbic acid (vitamin C) doesn't have a significant impact on antibiotic resistance. It is not a factor contributing to antibiotic resistance.
D. Antibiotics are taken with water or juice:
Whether antibiotics are taken with water or juice doesn’t directly influence antibiotic resistance. Proper hydration is essential to support the body's overall health, but it doesn't impact the development of antibiotic resistance.
Correct Answer is B
Explanation
A. Gut-associated lymphoid tissue (GALT): GALT is a component of the mucosa-associated lymphoid tissue (MALT) and refers to the immune cells found in the gastrointestinal tract. These cells play a significant role in local immune responses in the gut.
B. Bone marrow: The bone marrow is the primary site of blood cell production in the body. It contains stem cells that can differentiate into various blood cells, including B cells. B cells mature in the bone marrow.
C. Thymus: The thymus is an organ located near the heart and is crucial for the development of T cells. T cells mature in the thymus, where they learn to recognize self from non-self antigens.
D. Lymph nodes: Lymph nodes are small, bean-shaped structures that produce and store cells that help fight infection. While they are essential parts of the immune system, B and T cells are not originally derived from lymph nodes.
